In the February 1st post liked over 1,800 times, McKeithen says he believes he should follow the constitution as well as the laws of the state of Florida.
He says gun control proposals from president Obama concern him, and that he will oppose any legislation that would infringe on the second amendment rights.

"And the congress and the president can do whatever they like, but they are going to have to answer to the people. And the people have the basic law behind them," said JD Webster.
